ABSTRACT Improved periclase refractories are prepared by using an alkyd resin binder for tempering and pressing periclase grains into refractory shapes such as bricks. The pressed shapes are dried and fired. After firing, the refractory shapes are impregnated under vacuum with molten pitch and can then be used as lining in basic oxygen steelmaking furnaces. The fired refractory bricks have a greatly improved modulus of rupture at 1482°C. of :000-4000 p.s.i. The alkyd resin is generally incorporated in amounts of 2.5 to 4.5 weight percent. The green strength of the alkyd resin bonded bricks can be improved by adding a strong organic acid to the alkyd resin prior to mixing it with periclase grains. The green strength of bricks produced from such a mixture is between 30 and 40 p.s.i.
